ANN: A new version (0.2.8) of the Python module which wraps GnuPG has been released.

3 Sep 2011

      A new version of the Python module which wraps GnuPG has been
released.

What Changed?
=============
This is a minor enhancement and bug-fix release. See the project
website ( http://code.google.com/p/python-gnupg/ ) for more
information. Summary:

Better support for status messages from GnuPG.
The fixing of some Unicode encoding problems.
Quoted some command-line arguments to gpg for increased safety.

The current version passes all tests on Windows (CPython 2.4, 2.5,
2.6, 3.1, 2.7 and Jython 2.5.1) and Ubuntu (CPython 2.4, 2.5, 2.6,
2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11 has been used for the
tests.

What Does It Do?
================
The gnupg module allows Python programs to make use of the
functionality provided by the Gnu Privacy Guard (abbreviated GPG or
GnuPG). Using this module, Python programs can encrypt and decrypt
data, digitally sign documents and verify digital signatures, manage
(generate, list and delete) encryption keys, using proven Public Key
Infrastructure (PKI) encryption technology based on OpenPGP.

This module is expected to be used with Python versions >= 2.4, as it
makes use of the subprocess module which appeared in that version of
Python. This module is a newer version derived from earlier work by
Andrew Kuchling, Richard Jones and Steve Traugott.

A test suite using unittest is included with the source distribution.

Simple usage:
...
...
...
import gnupg
gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')
gpg.list_keys()
[{
  ...
  'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2',
  'keyid': '197D5DAC68F1AAB2',
  'length': '1024',
  'type': 'pub',
  'uids': ['', 'Gary Gross (A test user) ']},
 {
  ...
  'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A',
  'keyid': '0C5FEFA7A921FC4A',
  'length': '1024',
  ...
  'uids': ['', 'Danny Davis (A test user) ']}]
encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])
str(encrypted)
'-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n
\nhQIOA/6NHMDTXUwcEAf
...
-----END PGP MESSAGE-----\n'
decrypted = gpg.decrypt(str(encrypted), passphrase='secret')
str(decrypted)
'Hello, world!'
signed = gpg.sign("Goodbye, world!", passphrase='secret')
verified = gpg.verify(str(signed))
print "Verified" if verified else "Not verified"
'Verified'
